From d3eff1fcebc6d02d8cf11f499de9e219af43a92b Mon Sep 17 00:00:00 2001 From: nyash-codex Date: Fri, 28 Nov 2025 17:13:52 +0900 Subject: [PATCH] feat(joinir): Phase 45-46 read_quoted_from IfMerge implementation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 45: read_quoted_from JoinIR Frontend/Bridge - Implement lower_read_quoted_pattern() for Guard if + Loop with break + accumulator pattern - Add T1-T4 Route B E2E tests (all PASS) - Create phase45_read_quoted_fixture.hako for Route A testing Phase 46: IfMerge extension for loop-internal if-body reassignment - Add escape handling: if ch == "\\" { i = i+1; ch = s.substring(...) } - Use IfMerge to merge i and ch after if-body (speculative execution) - T5 PASS: "a\"b" → 'a"b' (escape handling works!)
